1355-1369
Flux 10…150%
Motor voltage corresponding to 10%….150% of flux as a percentage of
Nominal. Flux voltage. Measured during identification.
P1.8.9.16
662
Measured Rs voltage drop “RsVoltageDrop
The measured voltage drop at stator resistance between two phases
with the nominal current of the motor. This parameter is identified during
identification run.
This parameter defines the motor stator resistance as a voltage drop at
nominal current. The parameter value is defined according to motor nominal
voltage and the current and the actual stator resistance as

665
Ir: Add generator scale “IrAddGeneScale”
Defines the scaling factor for generator side IR-compensation when torque
boost is used.
P1.8.9.19
667
Ir: Add motoring scale “IrAddMotorScale”
Defines the scaling factor for motoring side IR-compensation when torque
boost is used.
P1.8.9.20
673
Measured Ls voltage drop “LsVoltageDrop”
Leakage inductance voltage drop with nominal current and frequency of the
